2009 VRSCDX Night Rod Special
....
...when I flipped the switch to RUN it started up without hitting the momentary START switch. This happened sporadically. Sometimes doing it, sometimes not. Giggling on the wires leading into the controls didn't seem to make a difference.
...
...
Any ideas? I would think there is an issue with the momentary START switch being faulty. That would explain it starting when just turning the bike the run, but would that also cause the bike to shut off during riding?...
...
I would need to know more history of work done on this bike prior to first issue. Also, are there are any DTCs (diagnostic trouble codes) set?

See here for how to read and clear DTCs.

I just recently purchased the bike and have not personally done any work to it. Looking back through the paperwork the dealership gave me from the PO. There was a tuner put on and removed by the dealership. This is all new to me by the way.

I followed your instructions and these are the codes that came up.

P - None
S - b1122
C - None
b - C1095, C1216

Pn 32783-08A

I am unsure if these were ever reset. So for all I know, these are all the codes that ever occurred over the life of the bike. I thought about erasing them and then taking the bike back out to see what comes up then but wanted to check with you first.

Thank you in advance for your help.
Whenever you read codes you should write what you see and then clear the stored codes. If a code reappears it is a current fault.

The codes you listed;
B1122 = right turn signal output fault = bad turn signal bulbs, right turn signal circuit (brown wire) is open, or you have a damaged HFSM (hands free security module) or IM (instrument module).
C1095 = front brake switch open & C 1216 = rear brake switch open = brake light ground wire open, bad ABS diode pack, front and rear stop lamp circuit bad (not likely), bad ABS ECU​
aren't likely to cause your starter problems but these do point to wiring problems in the handle bar controls that could involve the start switch.
